**Hybrid Statistics: The New Way to Calculate Statistical Significance**

## Our Hybrid Statistics combines Bayesian and Frequentist methods, calculating A/B Testing statistical significance with more speed and accuracy

## A/B Test Statistics **Reinvented**

Anyone running an A/B test needs to know two things: 1) how significant are my results 2) how long until my data is reliable?

There are two types of A/B testing statistics: Frequentist and Bayesian. Frequentist statistics use a fixed sample size and show how often an event occurs. Bayesian statistics measure the probability that a hypothesis (B converts more often than A) is correct. It shows you the size of the effect and the trust you can place in it.

The Convertize **Hybrid statistics** – combining Frequentist and Bayesian statistics – provides a series of metrics that help you decide when an A/B test is complete:

**Smart CR%**– your conversion rate, weighted towards recent performance**Confidence level**– how many times (out of 100) the same test would produce the same results**Duration estimate**– how many days until your test is reliable

**Test Hypotheses** Trust Numbers

Using a unique **Hybrid Statistics** to A/B testing statistics, Convertize tells you whether your data has captured a real change in your conversion rate. It then shows you how likely an edited page is to outperform the original. You can adjust your **Confidence Level** objective between 85 and 99%, shortening or extending the **Duration Estimate **for your experiment.

The **statistical significance calculator** incorporates more parameters than most A/B testing software platforms, in order to avoid false data and give you the most accurate results. This is why the reliability of your tests are described with a **Confidence Level** rather simply statistical significance:

- Avoid false positives
- Never waste traffic
- See how long a test will run
